    Possible issues due to rust...

    A friend left me a Colt BCG for storage which I decided to clean before doing so.
    Everything looked fine except for the bolt tail which was pitted with rust.
    Any possible cycling issues that may result from the pitting?

    Was this corrosion on the bolt tail under a layer of carbon?

    Some yes. There wasnt too much carbon on it. Some after wiping off what looked like diluted rust.

    Ouch.

    I hate seeing things in that condition.

    That is down right neglect. I have some other words but some people can't be convinced otherwise reference taking care of things.

    I would let it soak in some Kroil, then scrub it with a steel tootbrush, then go over it with some steel wool. Change the gas rings, maybe hit the inside with a .17 brush.

    That pretty much sums it up. I personally wouldn't use that bolt.

    I dont know how it was stored before having been turned over to me but from what I saw, it appears to have been cleaned before storage because it didnt have much carbon on it.
    So it's still re-usable after doing the above procedure??

    To be on the safe side and retracting what I said above, no. The manual states that if the cluster of pitting is larger than 1/8" diameter and if the appear o be deeper than .010", then no. The big area's of concern would be the face, lugs and cam pin hole.

    The -23&P is not very lenient on bolt carrier damage inspection limits. The -23 calls out specific inspection criteria for bolt face pitting, but as far as the rest of the bolt goes, any damage around the cam pin hole or locking lugs, is cause for rejection.

    As far as -23 standards goes, your bolt is unserviceable. Whether you want to risk using it, is completely up to you.

    Quib,
    Maybe you should post up your dunkit solution/instructions and have the mods/staff do a sticky in the FAQ.
    I think that might help the "pitted bolt" situation in the future.

    In Col_Crocs situation it was beyond his control,but this is becoming a common problem it seems.
